Equipment

  • Large oven-safe skillet (cast iron or heavy-bottomed preferred)
  • Wooden spoon or spatula
  • Oven mitts
  • Knife
  • cutting board
  • measuring cups
  • measuring spoons

Ingredients
  

  • 1 tablespoon olive oil
  • 1 small onion finely chopped
  • 2 cloves garlic minced
  • 2 tablespoons tomato paste
  • 28 ounces crushed tomatoes
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 pound potato gnocchi
  • 2 tablespoons unsalted butter
  • 1/2 cup fresh basil leaves torn
  • 8 ounces fresh mozzarella sliced or torn into pieces
  • 1/2 cup grated Parmesan cheese

Instructions
 

Sauté the Onion and Garlic:

  • Heat 1 tablespoon of olive oil in a large oven-safe skillet over medium heat. Add the finely chopped onion and sauté until translucent, about 3-4 minutes. Add 2 cloves of minced garlic and cook until fragrant, about 1 minute.

Add the Tomato Paste:

  • Stir in 2 tablespoons of tomato paste and cook for 1-2 minutes, letting it caramelize slightly to deepen the flavor.

Prepare the Tomato Sauce:

  • Pour in the 28-ounce can of crushed tomatoes. Season with 1 teaspoon of salt and 1/2 teaspoon of black pepper. Let the sauce simmer for about 10 minutes, stirring occasionally.

Cook the Gnocchi:

  • Add 1 pound of store-bought potato gnocchi directly to the skillet with the sauce. Stir to coat the gnocchi evenly, then cover the skillet with a lid. Cook for 5-7 minutes, until the gnocchi is tender and has absorbed some of the sauce.

Finish with Butter:

  • Stir in 2 tablespoons of unsalted butter until melted and fully incorporated, adding richness to the sauce.

Add the Basil and Cheese:

  • Stir in 1/2 cup of torn fresh basil leaves and half of the 1/2 cup of grated Parmesan cheese. Arrange the 8 ounces of fresh mozzarella pieces evenly over the top of the gnocchi. Sprinkle the remaining Parmesan on top.

Bake Until Bubbling:

  • Preheat your oven to 400°Fahrenheit (200°Celsius). Place the skillet in the oven and bake for 10-15 minutes, or until the mozzarella is melted, bubbly, and lightly golden.

Serve:

  • Remove the skillet from the oven and let it cool for a few minutes. Serve hot, garnished with additional fresh basil if desired.

Notes

Expert-Level Tips

  • Drain mozzarella if packed in water to avoid a watery bake.
  • Use a large spoon instead of a spatula when stirring in gnocchi to avoid breaking them.
  • Simmer low and slow to build a deeper, sweeter tomato flavor.
  • Broil with the door slightly ajar and keep a close eye—it browns quickly.

Serving Suggestions

  • Wine pairing: A glass of Aglianico or Montepulciano pairs beautifully with the richness of the tomato sauce and mozzarella.
  • Serve with a green salad with lemon vinaigrette to cut through the richness.
  • Add crusty bread for scooping up the bubbling tomato sauce, making this a hearty meal! 
  • Serve in individual ramekins for a fun dinner-party twist.

Storage Instructions

  • To store: Let the dish cool fully, then transfer to an airtight container or cover the baking dish tightly. Refrigerate for up to 3 days.
  • To reheat: Bake at 350 degrees Fahrenheit (175 degrees Celsius) until warmed through and bubbling.
  • To freeze: Assemble but don’t bake. Wrap tightly in plastic wrap and foil and freeze for up to 2 months. Bake straight from frozen, adding about 15–20 minutes to the baking time.
